Final answer:
To determine the displacement d of the cord from the wall when a force is applied, use Hooke's Law and calculate the displacement using the formula d = F/(k_BA + k_BC), where F is the force applied to the cord and k_BA and k_BC are the stiffness values of springs BA and BC respectively.
Step-by-step explanation:
To determine the displacement d of the cord from the wall when a force is applied, we need to use Hooke's Law which states that the force exerted by a spring is directly proportional to the displacement of the spring from its equilibrium position.Hooke's Law can be expressed as F = k*x, where F is the force exerted by the spring, k is the stiffness (force constant) of the spring, and x is the displacement of the spring from its equilibrium position.Therefore, to find the displacement d of the cord, we need to know the force applied to the cord and the stiffness of the springs BA and BC. The stiffness (force constant) is typically given in units of N/m (Newtons per meter). With this information, we can calculate the displacement d using the formula d = F/(k_BA + k_BC), where F is the force applied to the cord and k_BA and k_BC are the stiffness values of springs BA and BC respectively.
